I don't intentionally keep in touch with any of my classmates (don't do FB), but as i have said before, Burnley is only a small town and i regularly bump into the odd one now and again when out and about.
Incidentally, i did bump into one such guy a couple of months back in the barbers. Hadn't seen him for yonks and yonks and we had a decent chat, catching up with one another's lives. He had always been a bit of a rebel at school and i was slightly taken aback by learning he did a lot of voluntary work for those in his community, mainly the old. Just 3 weeks after seeing him, i read he had died from a heart attack and some of the glowing tributes to him brought a tear to my eye.
